It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

Checkin was painful and slow! Lady didn’t seem to know what was going on and couldn’t explain the delay. Seemed ahe couldnt see the computer scree and we couldn’t hear her talk through her mask.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

Seats are smaller and harder than other airlines we have travels with. Food was edible but no good. The sandwich was the only thing I would eat again. They did have a lot of movies to watch.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Booked a united Air flight with option to pick seat , then found out was on an Air Canada flight with assigned seat , then they wanted a several dollar charge for some 25 cent value entertainment listening ear device

It was fine. The flight attendant appeared to be in a bad mood but everything was fine.

Waited for our plane from HNL so we didn't miss connection. AMAZING Service for that, then really clean plane. Nice airline attendants.

Multiple maintenance delays and the missed and rebooked connection changed gates at least 6 times including one which had us walking 20 minutes to another terminal and then back again. Seated our family of three in different middle seats throughout the plane and then there was an empty seat next to me. Very long travel day which I would have never agreed to if I knew the itinerary would be changed at 5 am, 2 hours before takeoff.

It was as expected for such a short flight. No complaints

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Crazy seating issues. We got seated far apart. Offered middle seats at a premium rate. Why is a middle seat now the expensive seat? Baffling.

The boarding process was a nightmare and though we were traveling business class, we were in Group 2 and the organization was terrible. The Business Class on this flight was crowded and did not feel clean and nice. Overall, I would not travel Business again on the American Airline flight through British Airways Not nearly special enough for the considerable cost .

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

VERY disappointed at the agent checking in my luggage. I know that the weight limit is 23 kg, a little over 50 pounds (50.71 pounds). Yet the agent kept repeating "50 pounds". So I said, the limit is 23 kg, and she had the audacity to say 'no, it is 22 kg!" Imagine my surprise. Was she ignorant or was she poorly trained? Not sure. The boarding process was pretty good. The speakers were loud enough so I still could hear them despite inconsiderate passengers continuing to speak while the announcements were going on. During the flight, the teenage girl sitting behind me kept pressing her feet to the back of my chair. I turned around several times, yet she did not get the hint. I did not make a fuss since I sense I had a bad streak that night with AA, so I just did the best I can to lean forward and not let that bother me.

Seats were very uncomfortable. I paid extra for a seat with more leg room, the seat was no different than a seat at the back of the plane. Flight attendant was rude.

Very unfriendly crew, Air Canada should hire staff that are willing to do their job and be friendly to others. Unmannered flight attendants.

The fact that we have to check in our carryons when we met the requirements and there was plenty of spaces near we sat was ridiculous

Problem with operation of on board entertainment computer. Failed about 1 /2 hour into the flight. Rebooting failed to restore.

There was a terrible delay upon arrival in Barcelona. The plane had to park a great distance from the terminal, and only one bus was available to make the ~15 minutes each way trip, meaning it was ~ 45 minutes after we landed that I finally entered the terminal.

Hated charging my devices. The location of the outlet was inconvenient. And no USB connection. So outdated.

I was very good. Service was great. Seating selection was not too good.

Arrived at our connection to find out all 4 of our seats were moved in different parts of the aircraft. Traveling with two small children, this was not going to work. We spoke with the gate attendant and she was not helpful and downright rude. They could only “accommodate” having 2 seats together and this was an international flight. We will not be traveling with air Canada again unless there are absolutely no other options.

The mid flight snack could have been more substantial than tiny bag of pretzels.

Flight took off little late and landed back at YVR after an hour without informing a reason to the passengers. Also, second time also got late but an hour to take off. Therefore, I had to change my plans during due to delay in landing to SFO roughly about 6 to 7 hours.

. Crew was professional and friendly. Food could have been hotter

My flight was delayed d the gate was never updated inside the terminal. If I hadn’t checked my email I would have missed my flight. Also, I paid a total of $5100 for my flight to be. Business or first class. My final leg of my flight from Heathrow to Frankfurt was not to standard of what I expected or experienced in the previous legs of my trip.

I requested a wheelchair for they haven’t got it, they are old and don’t speech english

The real bathroom smelled horrible and it smelled in the real of the plane..

Good but entertainment system was not easy and very buggy

They gave us free up grade to a roomier seat.

The connection between my income flight and the outgoing flight was slightly late and they would not hold the next flight for 7 minutes. The next flight was 4 hours later and we were issued a stand by ticket. So we had to wait to find out if we would even be on that flight. After boarding that flight was delayed for 40 minutes because there wasn’t a ground crew to load the luggage. The airline is not living up to it reputation.

The flight was cold, no enough blanket and the crew said that they can’t change it. I got very sick in the flight . Most of the kids were coughing.

Plane was delayed about an hour but nice crew and service

Smooth flight. Safe airline. Professional crew. Glitchy entertainment touch screen. So-so food. So-so seat padding.

It wasn't clear that there will be additional charge for checked in baggage. Very, very disappointed making me pay extra $75. Food was not tasty and not healthy. Lufthansa used to be good, not any more. Unfortunately has gone down big time and continues to go down.

Flight delay and can’t much help passenger do the change connecting flight.

The seats in airbus from LA to London are uncomfortable. They are too narrow. I am a slim person but felt cramped. The way the seats are laid out really hinders privacy. You are forced to look at the person next to you which is awkward, Also the entertainment on the same leg was limited. The crew was excellent and attentive and the food was decent. The seats on London to Delhi leg were way better. The crew again was very attentive and polite.

Reasonably comfortable. Plenty of room. Crew were attentive and continually informing passengers of position. Although stuck in runway for 1 hour, weather issues, it felt like we were the crews first priority

British Airways canceled my flight and I had to fly on Lufthansa the next day. What a garbage airline 🗑️

The whole experience was great. The only improvement would be the entertainment selection

It was good overall. Entertainment was ok, one of the TV screens had issue. Bit old plane but leg space was good. Overhead luggage had good space. The worst part was experience at Heathrow airport, it was total chaos.

Lost our luggage going to Spain. Missed our connecting flight returning to home

It would be great to have at least two choices for a food, instead of just plain pasta 😏

Cabin crew were not nice. The plane was an hour late arriving.

Flight was on time. Boarding process was tedious. Not much overhead cabin space. Seats very close (front to back). Uneventful trip just the same.
